Hi,
Today running with a friend (who was wearing a Fenix with chest band), my 235 coupled with his band and showed me his HR instead of mine.
I did not do any prior coupling process with his chest band, but it automatically joined my device, changing the signal of my optical sensor by his signal.
It is easy to turn off the wrist optical sensor, but, how can I avoid any ant+ band to pair with my device and keep the optical sensor working?
Might be a silly question, but I only see 2 choices: Automatic (the optical sensor works unless there is an external band available) or "off for the optical sensor". I want "on" the optical and "off" external bands.
Thanks
